Windows 10: Restore Registry Backup With PC Not Booting

Windows 10 (64Bit)

If a PC's registry is backed up to a USB flash drive and after messing with the registry, for some reason, it won't boot normally. How do you restore the registry's backed up image? If I run a LiveCD (USB), that will only run with the portable Windows. The host's registry will not be seen, right?
Cheers

How to backup and restore registry using only win10 iso command prompt

In a link it suggested several registry troubleshooting steps for a Windows with black screen.

For Windows 10 1909 how do you backup and restore one registry change using a windows 10 iso command prompt?

If more than one registry entry is modified how do you backup and restore a second change?

In addition to modifying one or two commands how do you backup and restore the whole registry when the only access is via a windows 10 iso command prompt?

 

How to backup and restore registry using only win10 iso command prompt

The only access post windows upgrade is Windows RE using a windows 10 iso.

Registry steps may be needed that require deletion of the registry entries.

Aren't there two methods for backup: a single change and the whole registry?
I've never done either and need specific steps using Windows RE command prompt.
Also I've never restored a registry backup.
How do you restore a single backup using Windows RE command prompt?
And how do you restore the whole backup?

Again I've never done any significant changes in the registry and need specific steps using only the Windows 10 iso.

Hi,

Thank you for posting your query on Microsoft Community.

As per the description, I understand that you are facing some issues using Windows 10.

I would like to know some information.

• 
  What registry fix are you trying to run?
  
• 
  What is the exact issue that you are facing?
  
• 
  Have you taken a backup of all your data?
  

I would suggest you to take a backup of all your data before doing any changes in the registry keys. If you do any incorrect changes to the registry you won’t be able to boot the computer.
